iSpecification forming part of Letters Patent No. 199,454, dated January22, 1878,' application filed r October 29, 1877.

To all whom t may concern; Be it known that we, LEWIS C. LILLIE, of

`V Elizabeth, in the county of- Union and State l other lockingapparatus on the door.

We accomplish this by using a time-lock in connection with alockingmechanism placed on the jamb of the safe, the arrangement beingsuch that the time-lock may be placed either on the door or on the jamb,as may be most convenient.

Ourinvention consists comprehensively of an auxiliary locking mechanismplaced on the jamb of a safe or vault, in connection with a time-locklocated either on the jamb or on the door, the mechanism on the jamb andthe locking mechanism on the door being connected, so that'the former islocked by the latter.

The construction of our auxiliary locking mechanism and its arrangementin connection with the time-lock are shown in Figures 1 and 2, Fig. 2being a section through Fig. 1 along the broken line U V. Fig. 1 is aview ofthe back of the door and jambs, the door being closed. d Dis thedoor. J J J are the jambs. B B B are the bolts, which, together with thetie-bar H, form the train-bolts.7 4 I I' are the guides for the bolts B.They are securely bolted to the doorD. P is the combinationlock.

The above elements constitute the ordinary locking mechanism to be foundon safe and vault doors. f

The train -bolts are thrown by a 'spindle passing through the door, butwhich does not appear in the drawings.

The auxiiiarylocking apparatus which we use with the time-lock is shownon the jamb J. yIts principle and construction are as follows: The doorD swings on the hinge h., Fig. 2,V and its companion, which is notshown. Every point ofthe door, as the latter swings, describes an arc ofa circle, and consequently the edge m', Fig. 2, of the guide I does soalso, as shown by the dotted arc, Fig. 2. The guide I is always Vsetback from the edge of the door a short distance, in order that inswinging the door the edge ofthe guide may clear the edge of the jamlo;otherwise the door could not be shut, or, if shut, could not be opened,for the path that the edge of the guide I must travel when the doorswings would be blocked. `Similarly'if, by any means, the path of theedge of the guide I or any other point of the door be blocked, the doorcannot swing until such obstruction has been removed.-

The auxiliary locking mechanism that we have shown furnishes the meansby which such an obstruction is oered to the guide I by throwing thetrain-bolts, and which obstruction can only be removed by the unlockingof the time-lock, and is not at all affected by throwing back thetrain-bolts while the timelock is locked, which can be done, as thetimelock has no control over the train-bolts what ever. i f

Upon the jamb J of the safeor vault are placed the two lugs or blocl'sof metal u u, Figs. l and 2, rectangular in shape, and extending fromthe side wall W' to the edge of the jamb, or nearly so. These blocks uare of the Ysame thickness as the guide I. Thellugs are placed at somedistance apart, one being above the middle bolt and the-other below it.On each oi" them is a strap, i, through which passes the bar b', Figs. land 2, free to move upward and downward in a direction parallel to theedge ofthe jamb.

Extending om the bar b', one below each of the lugs a, are the arms aa', which bear the blocks of metal cl c. These blocks are just largeenough to fill the spaces-between the lugs u and the guide I, and are soheld by the arms a c that when the bar b' is raised the blocks will passinto and ll the spaces between the lugs u and the guide, therebypreventing any motion of the latter, and consequently the opening of thedoor. When the bar bis, lowered the block c comes opposite the recess rin the' guide I, which is deep enough to allow the guide to slip by theblock c' when in that position.

The arrangement of the recess fr in the guide is different from that ofrecess r. The former corresponds to the lower block c and the latter tothe upper block c. This difference and the effect of it will behereinafter described.

At the upper extremity of the bar b is the projection vo', Fig. 1, whoselower face or edge 1s at right angles to the length of the bar.

There is an elbow-lever above the upper lug u, which is pivoted to thejamb at o, Fig. 1.

The arm e of the lever has at its extremity the vertical pin z, whichbears against the lower face or edge of the projection o oi the bar b.The other arm, e', alsobears at its end the vertical pin z', whichextends above the level of the guide I.

It is evident that the revolving of the elbow-lever in a directioncontrary to that of the motions of the hands of a watch will raise thebar b and blocks o c, and inthe contrary direction allow them to fall.

Crossing the guide I and the tie-bar H on a level with the pin z' oftheelbow-lever is the bar b, Fig'. 1. One end of the bar b forms thetongue t, which extends into the time-lock T on the door, and the otherend bears against the lever-pin z. The headed pin p' passes lthrough theslot s in bar b, and screws into the guide I, forming a guide for themotions of the bar b.

The lug l, Fig. 1, on the face of the tie-bar E, projects through theslot s in the bar b,

in consequence of which the tie-bar, or, what vamounts to the samething, the train-bolts, cannot be thrown out without also moving ,thebar b toward the jamb J, which, pressing against the pin z on theelbow-lever, revolves the latter, and raises the bar b and blocks o c ofthe auxiliary locking mechanism, the latter passing into the spacesbetween the lugs u and theguide I. When the bar b is moved toward thejamb J by the train-bolts, thev tongue t is drawn from the time-lock T.

The trainbolts and bar b having been thrown, the former may be entirelyretracted without exerting any iniiuence over the bar b, as the lug Zwill slide in the slot s in the bar b". 1f the time-lock T has locked inthe meantime, the bar b, elbow-lever, and bar b of the locking mechanismwill remain unaltered in position, holding the blocks c c between thelugs u and the guide I, keeping the door closed. If, however, thetime-lock is unlocked when the train-bolts are retracted, the tongue tis free to pass back into the timelock, and the bar b may be moved backby the weight of the bar b and blocks o c, causing them to fall andrevolve the elbow-lever.

The falling of the blocks c c brings them opposite the recesses r r inthe guide, and allows the door to be opened.

The above arrangement admits the timelock to be placed on the door, and,while governing theV unlocking of the auxiliary locking mechanism,exerts no control over the movements of the train-bolts, andconsequently no strain can be brought upon the time-lock by means of thetrain-bolts or their spindle.

T, Fig. l, represents the time-lock placed upon the jamb underneath theauxiliary lock ing mechanism. Extending from the lower end of the bar binto the lock T is the tongue t', which is drawn from or passes backinto the time-lock, according as the bar b is raised or lowered. Hence,when the bar b is raised and the door locked, the tongue t is drawn fromthe time-lock, and only when the latter is unlocked can thebar b' falland allow the door to be opened. When the time-lock is placed upon thejamb, and not upon the door, the bar b is superfluous, as theelbow-lever can be so placed that the end of the .arm e will bearagainst the end of one of the train-bolts, by which it would be moved asby the bar b.

It is an important result of this method of locking safe or vault doorsthat no strain can be brought upon the time-lock other than th at due tothe weight of the bar b and the blocks c c, there being no way ofexerting any force upon it from the exterior of the safe or vault.

As before stated, and as shown in the drawings, the recess r in theguide I, corresponding to the lower block c, is dierent from the one rcorresponding to the upper one, c. The

recess r" is as long as the whole play of the block c", so that, were itnot for the sliding piece in the recess r, the block c" would at no timeoffer any resistance to the opening of the door. The sliding piece xjust half iills the recess r, being of the same breadth Yand depth, andone-half as long. The slide .r is under the ycontrol of an elbow-leverpivoted at o', one arm of which is attached to the piece w by means ofthe slot in the former and the pin on the latter. The other arm isconnected with the tie-bar H by the rod m. The effect of this is that asthe train-bolts are thrown out the piece x is moved to the lower half ofthe recess r, and as the train-bolts are thrown back the sliding pieceis moved to the upper half of the recess. Consequently, when thetrain-bolts are thrown out, which operation, besides locking the door,elevates the block c to a position between the upper half of the recessr" and the'lug u, and lowers the piece .fr to the lower half of therecess, leaving the upper half vacant, it follows that the block c canoEer no obstruction to the opening of the door D; but when thetrain-bolts are thrown back, and therefore the slide .fr is moved to theupper half of the recess r, the block c will preventthe opening ofthe'door, provided the timelock is not unlocked. If, however, it isunlocked, the bar b and block c" will fall, bringing the block c"opposite the lower` half of the recess r now vacant, and the door willbe free to be opened.

With both recesses r and r arranged in this manner, with a slidingpiece, x, the auxiliary locking mechanism would offer no obstruction tothe opening of the door until after the train-bolts had been retracted,and then only in case the time-lock was still locked, so that the bar band blocks c and c" could not fall.

With both recesses made as r', the auxiliary mechanism fastens the doorwhen the train-bolts are thrown; but when the trainbolts are withdrawnthey only` release the door, provided the time -lock is unlocked, whichallows the bar b and blocks c' to fall, and bring the latter oppositetherecesses.

We do not wish to limit ourselves to the particular mechanism shown.

Our invention may be applied in many different ways, and must bearranged to conform to the arrangement and the necessities of thelocking mechanism on the door.

We claim as our inventionl. The combination, with a time-lock, T, on thedoor, or a time-lock, T, on the jamb, of a safe or vault, of anauxiliary locking mechant ism placed on the jamb, and consisting of thebar b", elbow-lever, sliding bar b', and blocks c' c", working withreference to the lugs u and the guide I, having recesses r in it,substantially as and for the purpose speciied.

2. The combination, with a time-lock, T, on the door, or a time-lock, T,on the jamb, of a safe or Vault, of an auxiliary locking mechanism,placed on the jamb, and formed as described, in connection with theguide I, hay ing in it recesses r", containing a sliding piece, moved bythe elbow-lever, rod m, and the trainbolts, substantially as and for thepurpose specified.

3. The combination, on a safe or vault, of a locking mechanism on thejamb, the trainbolts on the door, and intermediate mechanism connectingthe two, and operating to lock the auxiliary mechanism on the jamb ontheturning of the train-bolt spindle, substantially as described.
